For glow two strokes *IF* I hand start them I always use two fingers on the face of a prop blade, right down near the hub. I still get plenty of power to flip the prop and know my fingers will be well out of the way by the next rotation. If the engine should kick back or some other unknown, only the broadest and flattest part of the prop can strike my fingers.....which is a lot better than a sharp edge or tip.

Except for deadsticks on the runway, electric starters are used wherever possible which makes the whole prop positioning issue irrelevant for starting.
